Industrial Control & Automation: The Past
•Unconnected to the Web
•Used proprietary
hardware and software
•Secure through obscurity
and isolation
10
© 2015 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL
Industrial Control & Automation: Present
• Converged IT and Industrial
Control systems into Operational
Technology (OT)
• This introduces additional
Complexity
• IT and OT systems now Connect
and communicate with each
other.

SHODAN: You Are More Connected Than You Know
• The image shows the number of exposed
internet connected industrial control
systems such as SCADA, found on SHODAN
• Many of these system owners are not
aware of this connectivity or of the risks to
their business
• Many may connect through third parties or
through undocumented or uncontrolled
corporate connections

19th December 2014 | News
Steelworks site was directly targeted using a very
sophisticated spear phishing and social engineering
method. Gained access onto the office network of the
facility then moved into the production network
which resulted in “massive damage to machinery.”
This incident is significant as this is only the second
time a reliable source has publicly confirmed
physical damage to control systems as the result of a
cyber-attack.

What is the Risk To Our Business From OT?
What is the impact of an outage at our plants?
• Cost of one day production outages at each plant?
• Number of sites and production days?
How exposed are we to Cyber Threats?
• What are the threats? How exposed to these threats are we?
• How Converged, Complex and Connected are OT/IT environments?
How often could an outage happen?
• Every Day? Every year? Every ten years?
